Raichi!!

Trama

After his father's dojo is destroyed by a mysterious man, a young boy named Raichi dedicates himself to becoming the strongest fighter. Years later, despite achieving champion status, he remains unfulfilled. He discovers an underground fighting ring where combatants possess special abilities, and the champion is the very man who ruined his dojo. However, Raichi is defeated before he can confront him. A strange creature then offers Raichi the power to heal his wounds, enabling him to challenge these super-powered individuals, but this transformation also turns him into a girl.
